    It initially run correctly. I can install a VM via this interactive
installation mode once. However, it encountered another error while I was
going to install with the same command another time. It seems that the
sockets path has been changed. I checked that the default socket path is:
/usr/local/var/run/libvirt/libvirt-sock, but it seems that the service is
looking for a socket located at '/var/run/libvirt/libvirt-sock' (see
'ERROR    Failed to connect socket to '/var/run/libvirt/libvirt-sock': No
such file or directory' in the following running script) . I searched at
livirtd.conf file but cannot find a place to reset this socket path. Could
you let me know how to get around this issue?

Here is the running script:


[root at XenTester libvirt-0.9.10]# libvirtd --help

Usage:
  libvirtd [options]

Options:
  -v | --verbose         Verbose messages.
  -d | --daemon          Run as a daemon & write PID file.
  -l | --listen          Listen for TCP/IP connections.
  -t | --timeout <secs>  Exit after timeout period.
  -f | --config <file>   Configuration file.
     | --version         Display version information.
  -p | --pid-file <file> Change name of PID file.

libvirt management daemon:

  Default paths:

    Configuration file (unless overridden by -f):
      /usr/local/etc/libvirt/libvirtd.conf

    Sockets:
      /usr/local/var/run/libvirt/libvirt-sock
      /usr/local/var/run/libvirt/libvirt-sock-ro

    TLS:
      CA certificate:     /usr/local/etc/pki/CA/caert.pem
      Server certificate: /usr/local/etc/pki/libvirt/servercert.pem
      Server private key: /usr/local/etc/pki/libvirt/private/serverkey.pem

    PID file (unless overridden by -p):
      /usr/local/var/run/libvirtd.pid

[root at XenTester libvirt-0.9.10]# virt-install --prompt
ERROR    Failed to connect socket to '/var/run/libvirt/libvirt-sock': No
such file or directory
